Abstract: A core intended to be used as a support for a roll of paper, especially toilet paper, is formed by winding at least one strip made of tissue, the strip being impregnated, at least locally, with starch so as to improve its stiffness. Thus configured, a core is provided having both a mechanical strength suitable for the envisaged use and a greatly improved ability to disintegrate relative to a cardboard core so as to allow it to be able to be disposed of directly in a toilet bowl without risk of blocking the soil pipe.

Abstract: A calendering roller used to manufacture textured nonwoven fabric including papermaking fibers is disclosed. The calendering roller includes a positive pattern that includes a basic element having a ring shape and a repetition of said basic element along multiple rows and columns substantially overall a peripheral surface of the calendaring roller. The ring defines an apex relatively to a center portion of the ring defining a cavity and a grinded surrounding zone. The ring includes at least one radial channel putting in communication the cavity and the grinded surrounding zone so as to define a discontinuous calendering surface. The repetition is regular except for multiple substantially longitudinally and transversally oriented regions. The regions are of limited size with respect to a calendering roller size and randomly distributed so as to define multiple random longitudinal and transverse lines in the textured nonwoven fabric including papermaking fibers, generating a cloth-like visual texture.
